SW7AVSCE-K1 - Overview

Samson's SW7AVSCE-K1 AirLine 77 AH1 Vocal Headset system offers a true wireless experience with no beltpacks and no cables, allowing complete freedom of mobility. The system includes the AH1 Headset Transmitter, along with the CR77 Wireless Receiver.

The AH1 Headset Transmitter is designed to go around the back of your head rather than over the top. This allows the transmitter to be attached directly to the headband, out of the way and completely unobtrusive, while being comfortable and secure during performances. The AH1 offers 14 hours of operation on a single AAA battery. For the AirLine 77 AH1 Vocal Headset system, the AH1 Headset Transmitter features Samson's QV condenser microphone element. The QV is designed with a unidirectional microphone and cardioid pickup pattern that rejects feedback. It's ideal for singers who require hands-free performance.

The core of the AirLine 77 AH1 Vocal Headset system is the CR77 True Diversity half-rack UHF receiver. It's designed to work flawlessly with AirLine UHF transmitters. Featuring dual tuned, molded antennea, a front panel display with large multi-segment audio level and RF level LED meters, and a large rotary volume knob that allows easy adjustment of audio output, the CR77 takes all of the guesswork out making your wireless system perform. Its synthesized PLL frequency control circuitry keeps the signal locked and true while the LED meters monitor the system's operation. The rear panel features balanced XLR and unbalanced 1/4" outputs allowing flexible connection options. Two CR77 receivers can be rackmounted together in a single space rack (adapter accessory sold separately).

With AirLine 77 AH1 Vocal Headset, you get complete wireless freedom that's good to go anywhere the music takes you.
